4 Claims. (Cl. 131-207) This invention relates to a smoking device ofthe water reservoir type.

An object of the present invention is to provide a smoking device inwhich said cover for the reservoir supports the passageway for conveyingthe smoke from the generating end to the discharge end 'and means forcondensing and removing tar and tar constituents from the smoke.

Another object of the present invention is to provide a smoking devicein which valve means are provided in the passageway for controlling theflow of smoke from the generating end to the discharge end of the vsmokeconveying passageway.

A further object of the present invention is to provide a smoking devicewhich is simple in structure, 'and is particularly efiicient inoperation and commercially feasible.

These and other objects and advantages of the present invention lwill befully apparent from the following description when taken in connectionwith the annexed drawings, in which:

Figure 1 is a perspective view of the 'smoking device of the presentinvention;

Figure 2 is a sectional view taken on the line 2 2 of Figure l;

Figure 3 is a sectional view taken on the line 3--3 of Figure 2; and

Figure 4 is a sectional Iview taken on the line 4-4 of Figure 2.

Referring in greater detail to the drawing in which like numeralsindicate like parts throughout the several views, the smoking deviceaccording to the present invention comprises an upstanding body having aclosed bottom 11 and an open top 12. A cover 13 closes the open top 12of the body 10 and a dom-e-shaped head 14 is positioned exteriorly ofand projects upwardly from the cover 13.

The dome-shaped head 14 has a passageway 15 extending transverselytherethrough and a hollow tube 16 has the intermediate part fixedlypositioned in the passageway 15 and has a portion adjacent one endexteriorly of and on one side of the head 14 and has a portion adjacentthe other end exteriorly o-f land on the other side of the head 14, theportions being indicated by the reference numerals 17 and 18.

The portion 17 of the tube 16 is ad'apted to hold a smoke producingarticle, such as a cigarette 19, and is provided with an eject-orembodying a slide element 21 slidably mounted in the portion 17 in aslot 22 provided therein and having a finger grip portion exterio-rly ofthe tube portion 17, as indicated by the reference numeral 23 in Figure2.

The other portion 18 lof the tu'be 16 has a bit 24 mounted thereinIfor'rotation about the longitudinal axis of the tube 16.

A receptacle 25 which is adapted to contain a charge of adsorbentmaterial such as silica gel and which includes a bottom 26 and anupstanding wall 27 extendf 2,805,670 Patented Sept. f 10, 1 957 ice ingabout the perimeter of the bottom 26 is positioned within the body 10land has a threaded part 28 of the wall 27 adjacent the top dependinglysupported in the under face -of the cover 13 as 'by the part 28 being inthreaded engagement with an nternally threaded collar 29 depending fromthe under face of the cover V13.

The cover 13 has an aperture 31 in registry With an aperture 32 providedin the tube 16 connecting the interior of the tube 16 with the interiorof the receptacle 25 and has another aperture 33 in registry with asecond aperture 34 provided in the tube 16 connecting the interior ofthe tube 16 with the interior of the body 10.

The bottom 26 of the receptacle 25 is provided with a plurality ofaperturefs 47 connecting the interior of the receptacle 25 incommunication with the nten'or of the body 10.

The body 10 and the bottom 11 are preferably formed of two piecesthreadedly and detachably secured together as at 46, so that the -body10 and bottom 11 may -be easily taken apart for cleaning.

The interior of the receptacle 25 adjacent to the cover aperture 31forms a condensing chamber for the tars and tar vapors produced in thetobacco smoke and the interior of thefbody 10 adjacent the cover:aperture 33 forms a further condensing chamber for the tar and tarvapors and other vapors that may not -be removed by the adsorbentmaterial in the receptacle 25 or by the charge of water in the lowerportion of the Ibody 10. Preferably, the level of the charge of thewater in the body 10 should be in the vicinity of -a point above thereceptacle bottom 26, as indicated by a dotted line in Figure 2 andidentified by the reference numeral 35.

-Means is provided fixedly securing the receptacle bottom 26 in |spacedrelation to the body bottom 11 and comprises an upright threaded post 36having its upper end formed integrally with the receptacle bottom 26 andhaving its lower end threadedly secured in a threaded socket 37 formedin the central portion of the body bottom 11.

Valve means is provided in the bit 24 for establishing communicationbetween the other end portion 1'8 and the one end portion 17 of the tube16 through the passageway 15, the receptacle 25, and the body 10. Suchmeans includes a plug 20 which is carried by the free end of anextension 38 which projects into the interior of the tube 16 and isfixedly secured to the adjacent end of the bit 24. The plug 20 isprovided with a first cutaway portion or flat 39 normally in registrywith the apertures 31 and 32 provided in the cover 13 and in the tube 16respectively, and with a second cut-away portion or flat 41 normally inregistry with the 'apertures 33 and 34 -similarly provided in the cover13 and tube 16.. Upon rotation of the bit 24 within the tube 16, theflats 39 and 41 move from their normal position to a position in whichthe plug 20 closes the aforesaid register-ing apertures 31 and 32, and33 and 34, respectively.

The bit extension 38 'is provided with a plurality of spaced collars, asindicated by the reference numerals 42, 43 and 43', each havingoppositely positioned flats providing a tortuous passage -for thetobacco smoke received from the interior of the body 10 through thepassage 44 provided in the -adjacent end of the plug 20. The bit 24 isprovided With a mouthpiece portion 45 of conventional configuration.

=In use, the body 10 is removed from the cover 13 by unscrewing the post36 from the socket 37. The receptacle 25 may then be detached from thecollar 29 and a charge of adsorbent material, such as silica gel or thelike, placed within the receptacle 25. The receptacle 25 is thenreplaced Within the collar 29 and screwed up tight. The body 10 is nextprovided with a charge of wat-er and is replaced with its upper enda'butting the cover 13 and with the post 36 threadedly lsecured into thesocket 37. A smoke producing article, such as a ig'are'tte, isthentplaced in'the portion 17 offthe tube 16`and is ignited. When thecigarette has been consumed, it is ejected from the open end of the tubeportlon '17 :hy moving the ejecto'r slide element`21ftoward the'` openend of the tube portion 17.

During'the smoking of the cigarette the 'smoke 'i-s drawnlthroughthealigned apertures 31 and 32 into the interior' of the receptacle 25where its tar andtar vapors are condensed upon the wall-s of thereceptacle 25 and are `a`ds`orbed by the adsorbent material placedwithin 'the receptacle 25.` The smoketis then ,passed through the-apertures `47 into'the body of'water contained within the body `10 andupwardly through the aligned apertures 33 and 34 ntothe space vformedbythe plug 20 -adjacentithe fiat 41 and thenc'e through the passageway44 into the' tottuous paissageformed by the collars 42, 43 i and `4S' ontheextension ,38 and into the bit 24 from wherice it'is drawn' into themouth of the smoker.

It will be found that the smoking device according tothepresentinventionprovides a cool smoke having most,iif not all, of the tars and tarvapors removed therefrom. The smoking device, according to the presentinvention, 'is easily taken apart for cleaning and is as easily treassembled.
